def foo(x=nil, a: x, b: nil)
[a,b]
end
#one, un-named arg assigns to a
foo("a val") # => ["a val", nil]
#named parameter "a" assigns to a
foo(a: "a val") # => ["a val", nil]
#named parameter "b" assigns to b
foo(b: "b val") # => [nil, "b val"]
#what about using all of them?
foo("a val 1", a: "a val 2", b: "b val") # => ["a val 2", "b val"]
